It's really frustrating to end up with a mess, and I would think it to be near impossible to tell from your photo what the problem is. That is a really good shot of your work, though Is this the wrap you are working on?
I think you may need to back a bit, to a row that you know you got right, and then continue :knitting: We've all been there, and we feel for you.
There may be something useful under "Fixing Mistakes" here.
Hope this helps, feel free to ask for help anytime.
